Sony NEX mirror-less camera system:

uses an even shorter sensor to lens mount distance than Micro Four Thirds system which in retrospect was probably NOT a smart idea, as unlike Olympus Micro Four Thirds, it would seem Sony is now unable to create a NEX camera with an optimally functioning sensor shift image stabiliser - a big pity seeing as Sony do have that technology and with their cooperation with Olympus, have access to the the amazing 5-axis image stabiliser technology Olympus uses in Micro Four Thirds system

HOWEVER, the E-mount diameter is large enough to permit use of full frame sensors allowing Sony the exciting option of 2 systems with the same mount - but again, the diameter of the mount is too small for effective sensor based IBIS with full frame sensors

uses new E-mount lenses but unfortunately the current range is poor, the price high and the size too big for the concept of a compact mirrorless camera.

can use Alpha-mount dSLR lenses via:

LA-E1 and LA-EA3 offer contrast detect autofocus for lenses that have built-in focus motors (i.e. SAM and SSD), but only manual focus with other lenses

the LA-EA2 and the new LA-EA4 use Sony's 'Translucent Mirror Technology' to offer autofocus with all Alpha lenses

the new models in late 2012 such as the NEX6, Sony appear to be abandoning their non-standard Minolta legacy hotshoe at last!

All Canon EF glass can be used on these cameras and via the Metabones Smart EF adapter or Sigma MC-11 adapter and you will have optical IS functionality if it exists on the lens, and aperture control on the body and varaible AF functionality.

in 2016, Sony developed a TTL radio remote flash system:

FA-WRC1M wireless radio commander

FA-WRR1 wireless radio receiver attaches to flash unit

can do 15 flash units in up to 5 groups but only up to 30m distance

FX full frame sensor E-mount cameras

Sony NEX E-mount cameras with full frame sensors designed to use Sony FE full frame lenses

ISO-standard hotshoe - at long last, finally Sony is ridding itself of the crazy Minolta legacy!!!!

kit comes with a new more compact 16-50mm F3.5-5.6 retractable power zoom lens

2011:

Sony NEX 7:

at last the NEX that addresses the issues of the initial models and makes it a very good camera

built-in 2.4 million dot high quality EVF on the left side of the camera - perfect!

tilt-LCD screen although not as nice as on the Panasonic GH series

unfortunately it has a 24mp sensor - why couldn't they stick with 18mp?
